In a topographic survey undertaken by Karman Surv.Corp. before any leveling is conducted. The engineersusually check whether the engineers level is in perfectadjustment. A two peg test is used to check whether theline of sight is in perfect adjustment and the followingrod readings are taken, with instrument set up near A,backsight on A is 1.623 m. and foresight reading on B is2.875 m. with the instrument set up near B, backsight onB is 1.622 m. and foresight on A is 0.362 m. Compute the difference in elevation between Aand B. What should be the correct rod reading on A togive a level line of sight with the instrument stillset up at B? What should have been the reading on B with theinstrument at A to give a level line of sight?
Surveying In order to locate the position (P) of a sounding boat, the angles APB & BPC subtended at P by three points A, B and C on the shore were measured with a sextant and found to be 28º 42’ 40” and 30º 28’ 20” respectively, the point B & P being on opposite of AC. The length of AB & BC scaled from a map were 662 m and 4662 m respectively, and the angle ABC was 60º 50’ 40”. Carry out all the necessary calculations to compute the distances PA, PB and PC.
When measuring a distance AB, and with respective to facing towards point B when standing at point A, the first taping pin was placed 1.35 ft to the left of line AB, the second pin was set 1.89 ft left of line AB, and the third pin was set 1.52 ft to the right of the line AB as the survey team attempted to correct their prior placements badly. The recorded distance was 734.33 ft. Calculate the corrected distance. (Assume four taped segments, the first three 200 ft each.)
There's a solutions here in barlteby but different values only. UPVOTE WILL BE GIVEN! PLEASE WRITE THE COMPLEETE SOLUTIONS AND LEGIBLY! FUNDAMENTAL OF SURVEYING The left and right water edges of a river are 3.75m and 65.25m, respectively, from an initial reference point. Verticals are located at distances of 11.25, 19.25, 27.25, 35.25, 43.25, 51.25, and 59.25m, respectively, from the reference point. The corresponding depths of verticals are 5.2, 9.7, 9.6, 10.0, 10.4, 10.0 and 4.2 meters. Mean velocities in the verticals are 0.16, 0.60, 0.75, 0.92, 0.97, 0.98, and 0.65 m/sec, respectively. Disregarding the end to sections, determine the following: Discharge & Mean velocity of the river.
